ZEPHYR MINI Decentralized Heat Recovery Device

Full Description

The BSK Zephyr Mini is a compact, decentralised single-room heat recovery ventilation (HRV) unit designed for small spaces that require efficient, continuous air exchange without complex ducting. Ideal for bedrooms, bathrooms, offices, and apartments, it is the perfect solution for retrofitting spaces with no existing ventilation infrastructure.

Operating through a ceramic heat exchanger and a reversible fan system, the Zephyr Mini alternates airflow every 70 seconds to extract stale air and supply fresh, filtered air—while recovering up to 90 % of the outgoing heat energy. This not only improves indoor air quality but also reduces heating and cooling demands.

Its ultra-silent operation and intelligent humidity sensor ensure optimal comfort throughout the day and night, even in sensitive or quiet environments. The unit can be wirelessly linked with other devices for synchronised operation and is easily managed via an included IR remote.

Key Features

• Up to 90% Heat Recovery Efficiency – Recovers and reuses heat from outgoing air, improving energy savings.
• Ceramic Heat Exchanger – Long-lasting and efficient for consistent thermal performance.
• Silent Multi-Speed Operation – Four fan speeds including an ultra-quiet Night Mode.
• Humidity Sensor – Automatically switches to extraction mode when humidity levels exceed user-defined thresholds.
• Wireless Pairing – Enables multiple units to work in tandem for balanced airflow.
• Remote Control Included – IR remote provides user-friendly operation of all core functions.
• No Ductwork Required – Perfect for retrofits or spaces without centralised ventilation.
• Low Power Consumption – Energy-efficient operation using as little as 1.4 W.
